If Madonna fans had any crazy notion of nicking some of her DNA from her dressing room, bad luck…

The paranoid star, 53, has ordered aides to leave no trace of her after she leaves gigs on her latest world tour.

In true diva style she set up a “sterilisation team” to wipe away any DNA that may have been dropped in her room on hairs, skin or saliva.

Hygiene freak Madge, whose MDNA tour arrives in Coimbra City, Portugal, tomorrow has also told ­organisers only her and her entourage are allowed ­backstage passes.

Concert promoter Álvaro Ramos, overseeing the ­Portuguese leg of the spectacle, said: “We have to take extreme care, like I have never seen for any other artist.

“We cannot even look at the dressing room, after it is ready, or even open the door.

“We can only enter after her sterilisation team has left the room. There will not be any of Madonna’s DNA, any hair, or anything.
